Beit known that I, JOHN W. IRDSEYE, a citizen ofthe UnitedStates, residing at Gor- Y specification i ham, in the county of Ontario and State of useful Improvements fin Grabs for Pump- New lYork, haveinvented certain new and Rods and Pipes, of which-the following is a i v kThe object of this invention is to provide a new. and improved form of device that will permit the recovery 0f a lost pipe and pump 4. rods in so-called driven wells. :This and other objectsof the invention will be fully .,-illustratedinthe drawings, described in the AVA l the end thereof.

In the vvdrawings,V

specification and pointedout in the claims at Figure l. is vertical section of the-(well casing with thelost pipe and pump. rod Itherein showing my apparatus., in use for the purpose of recovering 1t.

v ,Fig. Qis a large detail view of my improved device with a modification embodied therein.

Fig. 4 is a 'shownfwith v,the grab adapted to be used in connection therewith. ig i 'In the drawings like reference numerals y.indicate like parts.

. Reference numeral 1 indicates the well casing suchas is used in driven lor bored wells, which wells frequently extend to a depth of several hundred feet. r

titl

e, 2 indicates the water pipe and 3 the pump rod which is generally used to connect the' pump that is always used at the bottom of a well with a handle for operating the pump at the top of the well. In this case the pipe and pump rod are shown as they frequently appear lost in a well casing.

It will be understood that the water pipe.

is usually about 1% in` diameter and the well casing is ordinarily 5 or 6 in diameter, although the dimensions, are immaterial for the purposes of my invention. It will also be understood that the sucker rod is usuallyabout in diameter.

After the boring of the well is finished it is customary to lower the pump witha section of the pipe and the sucker rod into the well casing. An additional section of water pipe and sucker rod isthen .coupled on and the l.pump is lowered still further. In

'like manner additional sections of pipe-and sucker rod are' connected until the pump rests-hin its proper position at the bottom of Spcification of Letters Paten-tf purpose of being connected to fittings. It sometimes happens, however,

that after the pump and one or more sec,.

tions of water pipe and sucker rod have been connected thereto they will get away and dropdown into the well in which case the' well is useless until the pipe and pump have been removed and my device has for its purpose the removal of the water pipe and i sucker rod that-have been lost under such clrcumstances. n

Referrmg now to the drawings, reference numeral 2A indicates a sleeve having a cou lpling 3A at the outer end into which is secured a plug 4 to which is connected a rod or tube 5, which rod may be increased in length by the addition of sections according to the depth to which the device mustbe lowered into the well. To the bottom of the sleeve 2A is connected a coupling 6 having 'a cone shaped hood 7 fastened thereon projecting downwardly therefrom. lThis lcone shaped hood 7 is adjustable or expansible to fit the various dimensions of well casings in connection with which it is used and for this purpose is divided along the line `8 indicated in Fig. l2,the outer' section having a series of holes therein which may be made toregister with any of the three Series of holes 9, 9v shown in Fig. 2,two layers of metal being fastened together by bolts or any other suitable device. l

In 'de of the Vcone shaped hood 7 is fastene the deflecting device 10, the upper end of which is slotted as indicated at 11 between upwardly and inwardly inclined fingers 12.

In use this apparatus is lowered into the well casing luntil it comes into Contact with the pump' rod andpipe which iti'will then encircle, passing down around it and deiecting it to the middle of the casingv until the pipe passes between the fingers 12 with the pump rod 3 extending up into the sleeve 2.v The Q water pipe will then be in position to vbe en-l gaged with the nipples 13 or 14. The nipple4 14 is used wherethe pipe has 'a female threa."

at the top, the nipple being tapered so that iwi 'it will enter the opening at the top ofthe f pipe. If, however, the pipe has a male thread at the top, the nipple. 13 will be snb-v l I stitutedfor the nipple 14. The nipple 13 is provided with a female thread whlch tapers, expandingv toward the bottom so that it can envelop the top of the pipe and make enlio" ` and force them together lated from the top of the ivell rigid with the devices@ that the device'can be turned thereby and make tlirended engagement. if, however, the Well is too deep to permit of the use of therigid connection 5 the connection 5 and plug i will. be omitted and the 'apparatus will be handled otherwise by a device which ll will non' describe.

The sleeve if* is slotted at three places opposite each other et 120 degrees apart, which sots are itted with the dogs fifi. v inside o'lthe sleeve .is provided a grab 1S 'which con- .sists oil. n tube having' a nlug 19 at the top thereof, in which is Tias-tened a har 15 having' an eye 'lo at the tog) thereof. The grab 1S is clotted suitabhy to receive the doge'l' on the Sieeve 2f* and belen7 the ,(jrah i8 are the hat spring strips 20, nrfprahlv three in number, having the jaws "21, '2l at the bottoni thereof. which jaws will norinalliT stand just above the fingers l'hen the nnrtsarc assembled the dogs '17 ivili enpgage in the slotsrin thetube oit the grob 1S, the sleeve 2A beings,- thereby suepended troni the `grab i8 (See 4). lith the parte in this relation a rope 'will be attached to the eve 1G and the apparatus Will be lowered to any desirable dciith. "lYhen it cornes into engagement with the Water nine and pump rod the pine and pnnip rod will be deiiec'ted into engagement 'with the jaws '21, the npparatus being lowered until the Water pine comes .into Contact with the dogs 17 and as it is further lowered the dogs will be spread nntil. 'thev are forced out of engagement with the grzib'l. after which the sleeve 2A can drop, causing the tapered portion at the bottoni ot the coupling (5 to eng. 1with the dogs einst the pino and ciutch it. The grab and nf: nine can then mennen he. mis-,fed by the rope to the ton of the well. casing; a nd removed.
